Introduction: Upper limb arterial tree variations have being drawing attention of anatomists and surgeons since ages owing to the clinical significance attached to them. The main artery of the arm is the brachial artery which after giving branches to it terminates in the forearm. Aim: The present study aims at exploring the gross anatomy, embryological and applied aspects of the high termination of the brachial artery. Materials and Method: An unusually high termination of brachial artery into its terminal branches radial and ulnar arteries was noted during routine dissection in the upper part of the arm at AIIMS Rishikesh. The course, branches and relations of these arteries were studied and assessed in the light of available literature. Conclusion: High termination of the brachial artery implicates a huge applied importance for radiologists, physicians, orthopaedic surgeons. So, encountering such variations might be possible during diagnosis, surgical procedures or interpreting angiograms of the upper limb.

Dissection of the upper limb of a 67 year-old male cadaver revealed tortous bilateral brachioradial arteries; these originated in the proximal third of the arm. The left brachioradial artery originated from the brachial artery proper, while the right arose from the superficial brachial artery. The right median nerve was formed within the proximal 1/3rd of the limb from its unusually longer lateral and medial roots, the nerve coursing 3-4 cm distal to its formation passing through the brachial artery and the brachioradial artery forming an island pattern (an inselbildung). With an increased usage of the radial artery as a vascular access route over the femoral artery, Variants of the artery, its origin, morphology and topography are significant in selection of the artery for percutaneous transradial coronary catheterization. Such knowledge will minimize iatrogenic complications or vessel crossover rate. Combination of high-origin brachioradial artery together with tortuosity are unco...

The presence of both a superficial ulnar artery (SUA) and persistent median artery (PMA) of antebrachial type is of both clinical and surgical significance. In an 84-year-old female cadaver received through the Gift Body Program at Saint Louis University School of Medicine, the right brachial artery was seen divided into an SUA and radial artery (RA) slightly below the interepicondylar line of the humerus. At the level of the radial neck, the RA sent out the common interosseous artery that then gave off the radial recurrent artery before bifurcating into anterior interosseous artery (AIA) and posterior interosseous artery. The AIA continued to appear to branch into the anterior ulnar recurrent artery and posterior ulnar recurrent artery, as well as a PMA of the antebrachial type. In the hand, the SUA and RA contributed to the complete superficial palmar arch seemingly equally, and the RA was the dominant contribution to the deep palmar arch. Ninety-one other arms were assessed for this variation, and none were observed. Knowledge of an anatomical variation such as this may lead to decreased complications in the planning of surgical bypass grafting.
Variations in the Terminal Branches of Brachial Artery- A Cadaveric Cross-sectional Study
INTERNATIONAL JOURNAL OF ANATOMY RADIOLOGY AND SURGERY
Introduction: Brachial Artery (BA) begins as a continuation of axillary artery at the distal border of teres major, it appears in the cubital fossa, where it ends at the level of the neck of radius by dividing into radial and ulnar arteries. Common Interosseous Artery (CIA) is the largest branch of Ulnar Artery (UA) and arises in the cubital fossa. The terminal branches of BA at elbow are clinically important since they are responsible for the arterial supply to the forearm and hand. These arteries may get damaged during fractures of the elbow. Aim: To know the variations in the terminal branches of the BA at elbow. Materials and Methods: The present cross-sectional cadaveric study was done on 40 upper limbs from embalmed adult human cadavers in the Department of Anatomy, Kamineni Institute of Medical Sciences, Narketpally, Telangana, India, from August 2017 to August 2019. Dissection of BA in arm and cubital fossa was carried out according to Cunningham’s manual of practical anatom...
Superficial course of brachial and ulnar arteries and high origin of common interosseous artery
ijav.org
Knowledge of variations in the course and branching pattern of the arteries of upper limb is important for clinicians. We report the variations of the branches of brachial artery. The brachial artery was superficial throughout its course. It divided into radial and ulnar arteries in the cubital fossa. The ulnar artery passed superficial to the flexor muscles of the forearm as it leaved the cubital fossa. The common interosseous artery was large in size and it was a direct branch of brachial artery. It took its origin from brachial artery approximately 5 cm below the lower border of teres major muscle and followed the median nerve till the cubital fossa and divided into anterior and posterior interosseous branches. © IJAV. 2009; 2: 4-6.
Termination of the Brachial Artery in the Arm and Its Clinical Significance
2019
The variations in the arteries have been drawing attention of anatomists for a long time because of their clinical significance. The brachial artery is the principal artery of the arm which is the continuation of the axillary artery from the lower border of the Teres Major. It terminates into the radial and ulnar arteries below the elbow joint at the neck radius. The present study aims at exploring the clinical significance of the high termination of the brachial artery. During the routine cadaveric dissection of the arm, for the undergraduate students of medicine at our university, we observed a high bifurcation of the radial and the ulnar artery at the midshaft of the humerus. The median nerve was seen passing between these two junctions. Further, the course and the relations of this artery were studied. The accurate knowledge regarding these kinds of variation in the blood vessels is mandatory for planning of designing. General physicians, surgeons and radiologists should keep in...

International Journal of Anatomy and Research, 2019
Background: Knowledge regarding the course and termination of the radial artery before harvesting it for coronary artery bypass graft surgery (CABGS) is important. The brachial artery terminates at the neck of radius into radial and ulnar arteries. Purpose of the study: To know the various patterns of anomalous division ofthe radial artery. Methods: The study included 50 upper limb specimens from the Department of Anatomy, Sree Narayana Institute of Medical Sciences, Ernakulam. The specimens were fixed with 10% formalin solution and the radial artery was exposed from its origin till termination and observations were noted down. Results: The present study revealed that, radial artery usually was arising from brachial artery at the level of neck of radius. The variants observed included high bifurcation of brachial artery, division of radial artery into palmar and dorsal branches in the forearm and anomalous course of radial artery in the region of anatomical snuff box. Conclusion: The present study has revealed the anomalous division and course of radial artery around the wrist and anatomical snuff box and the knowledge of such anomalous course is important for diagnostic, interventional and surgical procedures.
Morphological feature of brachial artery and its clinical significance
Journal of Morphological Sciences, 2015
Introduction: The present study is to provide comprehensive data concerning the morphology of brachial artery which has a clinical significance for clinicians, orthopedics, vascular surgeons and anatomists. Materials and Methods: Routine dissections of the right and left upper limb of 34 adult cadavers (20 male and 14 female: mean age 78.9 year) were undertaken. It investigates the characteristics of the brachial artery such as the internal diameter, external diameter, wall thickness and distance of bifurcation of brachial artery. Results: The mean of the external and internal diameters of the brachial artery from proximal to distal ranged from 6.87-5.35 mm respectively. The bifurcation of the brachial artery from the head of radius into its terminal branch radial and ulnar artery ranged from 13.49-13.79 mm, while the distance of bifurcation of common interosseous from origin of the ulnar artery ranged from 33.11-33.45 mm. The angle of bifurcation of the radial and ulnar arteries from the brachial artery ranged from 5.79-7.33° and 18.640-19.36° respectively. Due to variability of the brachial artery in the upper limb, the surgical and invasive procedures are performed in the region such as artificial arterial-venous fistula become more difficult and may result in iatrogenic injury. Conclusion: Therefore, it is a clinical significant for surgeons to known the variable morphology and course of brachial artery to minimize surgical complication prior to operation.
